Yes actually I forgot to mention one important thing. I dont know if the name have a meaning in your native languages but in my language Slovakian Kožár/kozar as well as in other Slavic languages means Skinner devided from Skin (koža/koza) or pelt/fuhr kožušina/kozusina. Something like the man is skining animals of its pelt (maybe hunter that hunting animals for its pelt). Maybe it is just a coinsidence or native "adoption" of the name thats why I would like to find out if it has any meaning in other langueages. It could be easyer to locate that way.
